Observability costs are rising significantly as businesses seek to maintain high performance and availability, with global annual spending expected to reach 4.1 billion USD by 2028. The increase in costs is driven by the complexity of digital environments, the proliferation of microservices, ephemeral servers, and the use of chaos engineering. To manage these expenses, companies can adopt a DIY observability framework that categorizes data based on usage, limits data indexing to frequently searched information, and routes data to appropriate storage solutions. This approach minimizes unnecessary data generation and converts logs to metrics to reduce storage costs. Alternatively, organizations may consider off-the-shelf observability solutions, but should carefully assess vendors' cost optimization tools and pricing models to avoid unnecessary expenses.
